Fraunhofer IIS and Airoha Technology are presenting a breakthrough multi-channel spatial audio solution for next-generation wireless headsets at Mobile World Congress (MWC) 2026.
The collaboration integrates Fraunhofer’s industry-leading LC3plus codec and upHear Cingo spatial audio rendering solutions with Airoha’s flagship Bluetooth® SoC, the AB1595 – enabling high-definition, low-latency, and resilient wireless multi-channel audio tailored for premium mobile and XR applications.
At the core of this joint solution is a seamless, high-definition multi-channel wireless transmission chain designed to meet the evolving demands of mobile devices, extended reality (XR), and immersive media ecosystems. By leveraging Airoha’s proprietary High Data-rate Technology (HDT), the AB1595 platform provides the robust bandwidth required to support Fraunhofer’s LC3plus codec. This combination delivers high-resolution audio with efficient bit rates and ultra-low latency – essential for scalable, multi-channel headset designs that go far beyond traditional stereo limitations.
Complementing the transmission pipeline, the upHear Cingo binaural rendering technology by Fraunhofer IIS transforms multi-channel content into an immersive 3D sound experience directly on the headset. upHear Cingo delivers lifelike audio for streaming, gaming, immersive communications, and next-generation media services. For complex multi-channel content, upHear Cingo combines excellent timbre preservation with efficient low-power performance, which is critical for mobile and wearable devices.
Dynamic spatial audio with head-tracking is a key enabler for immersive media and XR use cases. It is supported by the CyweeMotion sensor fusion technology and enables single- and synchronized dual-ear IMU sensor modes for TWS and OWS designs, delivering stable and responsive head-tracking performance across form factors.
To ensure reliable performance even in the congested RF environments of dense urban and trade show settings, the solution incorporates Fraunhofer’s LC3plus Advanced Packet Loss Concealment (PLC), enhancing stream continuity and resilience. Combined with Airoha’s HDT, the system delivers a robust, high-throughput wireless audio experience optimized for modern mobile networks and device ecosystems.
The Airoha AB1595 provides a highly open and developer-friendly DSP platform that allows advanced third-party algorithms such as Fraunhofer’s to run efficiently. “Airoha is dedicated to providing an open and robust platform that empowers our partners to push the boundaries of wireless audio,” said Yuchuan Yang, Senior Vice President of Airoha Technology. “The AB1595 is designed to seamlessly support sophisticated third-party algorithms. We are proud to collaborate with Fraunhofer in enabling immersive, scalable multi-channel audio experiences for the next generation of connected devices.”
